At present, hard brittle material cutting technique mainly contains cylindrical cutting, inner circle cutting and saw blade cutting.Although cylindrical cutting is easy and simple to handle, rigidity of saw blade is poor, and the easy sideslip of saw blade in cutting process, causes the depth of parallelism of cut workpiece poor; And inner circle cutting can only carry out straight cuts, surface incising cannot be carried out.Wire sawing technology has that joint-cutting is narrow, efficiency is high, chipping qualities is good, the advantage such as march Linear cut can become the cutting technique extensively adopted at present.Existing scroll saw is shuttle, and as shown in Figure 1, be current the most widely used cutting equipment in Opto-Electronics Crystals industry, it is by control system 1 for its theory structure, fixed head 2, organism frame 3, underframe 4, Feed table 5, scroll saw 6, drive wheel assemblies 7, tensioning wheel assembly 8, cylinder 81, guide wheel assemblies 9 forms, and various wheel assembly is fixed on fixed head 2, and fixed head 2 is fixed on organism frame 3, and organism frame 3 is fixed on underframe 4, and scroll saw 6 is in drive wheel assemblies 7, tensioning wheel assembly 8, guide wheel assemblies 9 is wound around, tensioning, cuts the workpiece 20 on Feed table 5, and fixed head 2 has the yielding window 21 of workpiece, operation principle is as follows: respectively have one group of drive wheel assemblies 7 in the left and right of making a concession window 21, tensioning wheel assembly 8, guide wheel assemblies 9, drive wheel assemblies 7 is respectively connected with a motor, is driving wheel during work, and another side is driven pulley, during as being wound with the diamond fretsaw of a section tens kilometers when left side driving wheel, first the end on left line wheel is passed through regulating wheel, directive wheel guides to the driving wheel on the right, and be finally fixed on by end on the driving wheel on the right, left and right cylinder pushes away regulating wheel by scroll saw tensioning simultaneously, the motor in synchrony of left and right sidesing driving wheel starts in the same way, left driving wheel starts unwrapping wire, and right driving wheel starts take-up, and workpiece rises and does feeding cutting movement.After left driving wheel unwrapping wire terminates, motor reversal, two driving wheels start oppositely to put take-up.So repeatedly complete the cutting to workpiece.There is its own shortcomings in it: owing to adopting left and right cylinder tensioning, and must be synchronous, and this needs a set of improving and the pneumatic control system of maturation, meanwhile, left and right motor also needs synchronously, and manufacturing cost is higher, system complex, control difficulty comparatively large, be unfavorable for the maintenance in later stage.
Summary of the invention
The defect that the device that instant invention overcomes existing saw blade cutting exists, provides one and utilizes gravity as tensile force, the simple cantilever horizontal loop cutting machine of control system.
The technical solution adopted in the present invention is a kind of cantilever horizontal loop cutting machine, its main points are that it includes cantilever, column, Feed table, scroll saw, drive wheel assemblies, tensioning wheel assembly, guide wheel assemblies, electrical control cabinet, a drive wheel assemblies, tensioning wheel assembly and two guide wheel assemblies composition quadrangles, scroll saw is around on four wheels, for making a concession window in the middle of cantilever, various wheel assembly is fixed on cantilever, be positioned at the both sides of making a concession window, two guide wheel assemblies are individually fixed in the below of both sides, for the base of quadrangle, drive wheel assemblies, tensioning wheel assembly is individually fixed in makes a concession window both sides, above guide wheel assemblies, cantilever is fixed on column, Feed table is positioned at the below of making a concession window, drive wheel assemblies and drive motors are connected, drive motors is electrically connected with electrical control cabinet, tensioning wheel assembly hangs with counterweighted take-up.
The present invention changes existing reciprocating Linear cut into swinging, greatly reduce diamond wire length, only driven by a motor, a drive wheel assemblies drives other three wheel assemblies by scroll saw, and one of them is tensioning wheel assembly, and two other is guide wheel assemblies, stepless time adjustment can be realized, be convenient to the adjustment of technological parameter, frame for movement and control system are simple, production cost and maintenance cost low.
Counterweighted take-up is made up of connecting plate, guide rail, slide block, fixed pulley, weight, guide rail is fixed on connecting plate, slide block hangs over guide rail, the axle bed of tensioning wheel assembly is fixedly connected with slide block, and stay cord one end of weight is walked around fixed pulley and is fixed on outside axle bed, and the other end is connected with weight, weight naturally droops, connecting plate has the elongated slot slided for tension wheel shaft, connecting plate is fixed on cantilever, and cantilever also has identical elongated slot with the corresponding section of connecting plate elongated slot.
The pulling force utilizing fixed pulley the gravity of weight to be become level carrys out the tensile force as scroll saw, reduces a whole set of air supply systems such as cylinder, and structure is simple, failure rate is low.
The invention has the advantages that integral mechanical structure and control system are simple, failure rate is low, production cost and maintenance cost low.
